A map entitled "Allegheny Township Zoning Map" is hereby adopted
as part of this chapter. The Zoning Map shall be kept on file available
for examination at the office of the Township Manager. The map shall
be signed and attested by the Township Manager and shall bear the
seal of the Township. As soon as is reasonably practical after said
adoption, all amendments affecting district boundaries shall be noted
on the map by the Township Engineer, including date of adoption, and
shall be attested to by the Township Manager.
The Township is divided into the districts stated in this chapter
as shown by the district boundaries on the Zoning Map. The districts
are:
R1
|
Single-Family Residential District
|
R2
|
Agricultural/Residential District
|
R3
|
General Residential District
|
C1
|
Planned Shopping Center District
|
C2
|
Neighborhood Business District
|
C3
|
Highway Commercial District
|
I1
|
Light Industrial District
|
I2
|
Manufacturing District
|
RC
|
Riverfront Conservation District
|
TC
|

|
District boundaries shown within the lines of roads, streams
and transportation rights-of-way shall be deemed to follow the center
lines, except when said boundary is defined by courses and distances.
Such courses and distances shall govern. The vacation of roads shall
not affect the location of such district boundaries. When the Zoning
Officer cannot definitely determine the location of a district boundary
by such center lines, by scale or dimension stated on the Zoning Map
or by the fact that it clearly coincides with a property line, he
shall refuse action and the Zoning Hearing Board, upon appeal, shall
interpret the location of the district boundary with reference to
the scale of the Zoning Map and the purposes set forth in all relevant
provisions of this chapter.
These general regulations shall apply in all zoning districts:
A. In the R1, R2 and R3 Districts, any use not specifically listed in the district as a permitted use, conditional use or use by special exception shall not be authorized in that district. In the C1, C2, C3, I1, I2 and RC Districts, any use not specifically listed in the district as a permitted use, conditional use or use by special exception shall not be authorized in that district unless the Zoning Hearing Board, in its sole discretion, grants such use as a use by special exception after determining that the proposed use meets the applicable express standards and criteria of §
250-110A(42) of this chapter for comparable uses not specifically listed.
B. In the case of a land development, as defined by this chapter, approval
of a land development plan, as herein defined by the Board of Supervisors
in accordance with the requirements of the Township Subdivision and
Land Development Ordinance shall be a prerequisite to obtaining the permits required by Article
XXI of this chapter.
C. Accessory structures which are customarily accessory to principal
structures or uses authorized as uses by special exception shall be
permitted as accessory uses by right.
D. On farms, principal farm buildings and structures may occupy the
same lot as a single-family dwelling; however, three or more single-family
dwellings shall not occupy the same lot.
E. Except as noted in Subsection
C, in the R1 and R2 Districts, a single-family dwelling shall be the only principal structure on the lot. In the R3 District, only one single-family dwelling or one two-family dwelling shall be permitted on the lot. When authorized as a conditional use in the R3 District, two or more townhouses or garden apartment buildings may occupy the same lot. When authorized as a conditional use in the R2 or R3 District, a conversion apartment in an accessory structure may occupy the same lot as the principal structure containing an existing single-family dwelling or two-family dwelling.
F. In all districts, accessory structures may be located on the same
lot with the principal structure to which they are accessory or on
a lot which is immediately adjacent to the lot on which the principal
structure is located.
G. In the C1, C2, C3, I1 and I2 Districts, several authorized uses may
occupy the same lot or structure, provided that all applicable requirements
for each of the uses can be met on the lot.
H. In all districts, the minimum road frontage, as defined by this chapter, for any lot which fronts on any state, county or Township street shall be 50 feet, except as noted in Article
XIII.
I. Group homes shall be allowed as a use by right in all zoning districts
that allow single-family homes.
